Thanks for the reply, I’ll try to disassemble and post more detailed pictures…

You see the front has a piece that looks like a drawer facing? When you open it, there are 2 rectangular filters, one on top of the other. Obviously, suction is from the top and is blown out the bottom.

The reasons that I’m really wanting this to work out is 3 fold…I already own it, it was expensive, and it’s super quiet.
